About Us

ASTRL Lab Grown Diamonds creates our own, high-quality grown-diamonds in our state-of-the-art laboratory. Each unique diamond never receives post-growth treatments to enhance their beauty. Lab grown diamonds are chemically and physically the same as natural diamonds produced by the pressure of mother nature. Though, this process does not disrupt earth's crust as no mining is required.

Like Love • Everything beautiful must blossom and grow.

Our diamonds start from a diamond seed and grow inside controlled conditions that mimic the extreme temperatures and pressure of mother nature, just without the billions of years of waiting . Once the growing process is complete, each rough diamond must pass a rigorous quality inspection, and is then selected a shape for it's maximum brilliance, cut and polished by our family of diamond experts.
